Title: Detecting method of trouble point in two-circuit transmission line
Inventor: YAMAGUCHI KOICHI
IPC: G01R31/08
Filed: 1988-02-22
Abstract: PURPOSE:To assume a trouble point in a two-circuit transmission line, by using a trouble current ratio of two circuits at a power supply terminal before trouble interruption. CONSTITUTION:In the case when a trouble occurs at a point 7 in the course of transmission from a substation A (terminal A) 1, breakers 12, 14 and 16 are opened by a protective device of each substation. Prior to the operation of the breaker 12, a measuring device 8 measures trouble currents IA1 and IA2 by current transformers 17 and 18. The measurement is conducted by rectifying and integrating the currents for several tens of milliseconds from the occurrence of the trouble to the interruption thereof. When a power supply of the capacity of 1/10 of that of the terminal A is present at a receiving terminal Band the trouble current ratio IA1/IA2 is (x), the distance from the terminal A to the trouble point is ynot equal to y'. This distance varies when the capacity of the power supply at the terminal B varies. The trouble point can be determined primarily when it is assumed by using the difference/sum of the trouble currents of two circuits in the above ratio of the capacity. According to this constitution, error compensation corresponding to the system conditions of a transmission line can be executed, the precision of assumption of the trouble point is improved sharply, and labor-saving in a maintenance operation can be realized.

IPC: G01N27/00
Filed: 1982-03-12
Abstract: PURPOSE:To decide the genuineness of gold metal simply and rapidly, by measuring the electric conductivity of gold metal containing 99% or more gold. CONSTITUTION:Because the electric conductivity of gold is 74.5 (IACS%) and is extremely high as compared to other inexpensive metals, if the purity of gold is 99% or more, the genuineness of the gold bullion can be easily examined by simple measurement, that is, the measurement of the electric conductivity thereof. The measurement of the electric conductivity of gold metal is carried out by a method wherein an insulated coil through which a current is passed is contacted with the gold metal to be examined to measure counter-electromotive force generated to the coil by overcurrent generated in gold metal or the voltage generated by a current flowing between two adjacent points of gold metal is measured.

Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To execute special reproduction without making a user complicated key operation at a reproducing time by recording at least either one side be tween a command repeatedly reproducing the data recorded on a prescribed section in a data recording area and the command temporarily stopping the reproducing of the data after the data recorded on the prescribed section are reproduced on a character information recording area. SOLUTION: At least either one side between a loop command LP repeatedly reproducing the data recorded on the prescribed section in a data storage area or a pause command PS temporarily stopping the reproducing of the data after the data recorded on the prescribed section are reproduced is recorded on a storage medium (MD, CD etc.), having a data storage area and an additional information storage area containing character information. When the data are reproduced from this recording medium, such a special reproducing operation is performed by reading out this command information. Thus, when a power source is re-turned on, or the recording medium is replaced, the complicated key operation is eliminated.

Abstract: PURPOSE:To obtain a compact and light-weight display device having high operability at a low cost and with the simple assembly, by using a lower base, a slider and the display device main body and attaining the rotation and tilt functions through the joint part between the lower base and a slider and the joint part between the slider and the device main body respectively. CONSTITUTION:When the tilt of a display device main body 2 is desired, a cover 30 of the main body 2 is pushed back and forth or up and down. Then the projected area of the main body 2 slides the surface of a recess part 44 of a slider 19 and a post 4 moves relatively along an oblique groove 11 formed at the bottom part of the main body 2. Thus the main body 2 is tilted at a desired angle. When the rotation of the main body 2 is desired, the force is applied horizontally to the main body 2 to rotate it clockwise or counterclockwise. Thus a projected area 32 formed at the bottom of the slider 19 slides over the surface of a recess part 3 of a lower base 1 centering on the post 4. Then the main body 2 is smoothly rotated at a desired angle. This rotation is possible even in case the main body 2 is tilted at a desired angle.
